X. campestris pv. vitians is represented by two phenetically and genomically distinct bacterial populations (Vauterin et al. 1995). The pathotype is referred to Xanthomonas axonopodis pv. vitians, but the fact that this single strain differs uniquely from the other strains from lettuce (Lactuca sativa L.) suggests that it may be mis-labelled, or may have been inappropriately selected as the pathotype strain. All other strains are referred to X. hortorum, but evidence is lacking that these represent a distinct pathovar.

            The epithet was proposed as a synonym of X. vesicatoria based on a misunderstanding of the Code (Rule 28a) and without a description or a type strain. It must therefore be invalid according to the Code (Rule 15; Rule 24a) (Young et al. 2001b).
